Are you using Outlook Express? IE6 is a browser and not for email. Please be clear about what program you are using and then you might get some responses. :-)
Basically what you are doing is looking for the BCC line. How you get it depends on the program. If it's OE then start the message, click on the VIEW menu and select ALL HEADERS. Put everyone's address here. But, put yourself in the To line as some pop servers will reject emails with nothing in the To line.
